Product details
Overview
SAF-XC164TM-4F20F AA from Infineon Technologies is a 16-bit single-chip microcontroller based on the C166SV2 core, featuring 32 KB on-chip Flash, 2 KB dual-port RAM (DPRAM), and 2 KB program/data SRAM (PSRAM). It operates at up to 40 MHz CPU clock (25 ns instruction cycle), supports 14-channel 10/8-bit ADC with 2.55 µs conversion time, and integrates ASC0/ASC1 and SSC0/SSC1 serial interfaces. It targets real-time motor control and industrial embedded systems requiring deterministic timing and mixed-signal integration.
For engineers reviewing the SAF-XC164TM-4F20F AA datasheet, SAF-XC164TM-4F20F AA pinout, SAF-XC164TM-4F20F AA application, or SAF-XC164TM-4F20F AA equivalent, key selection criteria include its 40 MHz C166SV2 core performance, 32 KB Flash memory size, 14-channel ADC resolution and speed, integrated PEC for zero-latency peripheral event handling, and TQFP-64 RoHS-compliant packaging for industrial PCB layouts.
Technical Context
The SAF-XC164TM-4F20F AA implements a 5-stage pipelined C166SV2 CPU with single-cycle multiplication, 21-cycle background division, and MAC instructions-enabling deterministic execution in motor control loops. Its interrupt system delivers 63 sources across 16 priority levels with 50 ns sample rate, synchronized to peripheral events via the 8-channel Peripheral Event Controller (PEC).
On-chip peripherals include a 16-channel CAPCOM2 unit for PWM generation and capture, a 5-timer GPT12E unit supporting dead-time insertion and reload synchronization, and dual high-speed synchronous serial channels (SSC0/SSC1) operating up to 10 Mbit/s for encoder or sensor interface applications.

FAQ
What is the maximum operating frequency of the SAF-XC164TM-4F20F AA CPU?
The SAF-XC164TM-4F20F AA CPU achieves a maximum operating frequency of 40 MHz, delivering a 25 ns instruction cycle time with single-cycle execution for most instructions. This is enabled by its 5-stage pipeline and internal PLL, which accepts external clock inputs from 1 MHz to 20 MHz and scales them to the required core frequency.
Does the SAF-XC164TM-4F20F AA support CAN communication natively?
No, the SAF-XC164TM-4F20F AA does not include an on-chip CAN controller. It provides two asynchronous/synchronous serial channels (ASC0/ASC1) and two high-speed synchronous serial channels (SSC0/SSC1), but no CAN 2.0B or FD interface. For CAN-capable derivatives, consider the XC167CI series.
How much SRAM is available for user variables and stack operations?
The SAF-XC164TM-4F20F AA provides 2 KB of dual-port RAM (DPRAM) and 2 KB of program/data SRAM (PSRAM), totaling 4 KB of on-chip SRAM accessible without wait states. There is no separate data SRAM (DSRAM) in this derivative, as confirmed in Table 1 of the datasheet.
Is JTAG debugging supported, and what debug capabilities are included?
Yes, the SAF-XC164TM-4F20F AA includes full On-Chip Debug Support (OCDS) via a standard 5-pin JTAG interface. Capabilities include non-intrusive breakpoints, real-time register and memory inspection, instruction trace, and flash programming-all compliant with Infineon's OCDS specification for the C166SV2 architecture.
